What it does
Combines document management, ingestion and a chat interface into one deployable system, so an internal knowledge base with a usable front end is a Docker compose away rather than a project. Documents reach whichever model you configure, which decides whether it suits confidential material or wants a local model instead. Multi-user deployments need an answer to who can see which documents before the first upload. Apache-2.0.
